    Hello guys and girls



    I have a problem, when i connect my macbook pro to my sony TV its shows video and sounds as it should. but when i close the lid on the mac it dissapears and goes into blackscreen as nothing is connected, and no matter what i do i cant get video back. but when i connect to a new TV i get the video and audio..

    when i go from HDMI 1 where its connected to HDMI 2 and back to HDMI1 its shows shortly blue screen as it always does when its get connected but its still shows no video output

    anything is helpful thanks in advance.. Robin

    Just adjust your settings so that when you close the lid it doesn't sleep your mbp.

    Also, you can turn your brightness all the way down and the backlight on your screen will turn off if you just want to keep it open.

    Solutions:

    1.) Install NoSleep - http://code.google.com/p/macosx-nosleep-extension/downloads/detail?name=NoSleep-1.2.0.dmg&can=2&q=

    As per the description, it prevents sleep when the lid is closed. Select how you want it to behave in the System Preferneces.

    2.) Pick up an Apple Remote or connect a USB mouse to your MBP. After you close the lid, move the mouse around or push a button on the apple remote. The Mac will wake up and work as expected.

    You're welcome. Enjoy.

    I do not have a MBP yet but does it have output preferences? My PC was in DVI mode so HDMI would not work.

    When you close the lid, you're making the computer sleep.

    Plug in a USB mouse and keyboard, let it sleep, and then press a key or click to wake it up, your TV will now be your primary display and everything should work nicely.

    as i said earlier i tried that, and it does work with another TV just not the tv where i closed the lid where it was connceted, is there a way to like "delete the tv" from my Hdmi "list" so i have to found it again?..

    Ps when i connect a new hdmi to dvi adapter it works until i close down the lid, so its like destroying my adapter when the lid goes down..

    problem connecting macbook pro to tv HDMI

    When cable is connected to tv and mac:
    1) Select SOURCE HDMI 1 on your tv
    2) on Mac, go to System Preferences>Display>Arrangement>Mirror or Copy

    That worked for me. Good luck! :eek:
